Black obsidian Ring, Gemstone Rings, Minimalist Ring, Prong ring, Promise Rings, Anniversary Gift, Gift for her, Black stone ring, Boho ring Metal:- Brass Gemstone: Obsidian ✦ Our rings are made of high-quality Brass metal and are carefully crafted by hand in our family workshop. The brass metal will develop a nice antique color over time. So, I suggest cleaning it once in a while for getting back to the shiny original color. You can use natural ingredients like lemon or vinegar with water to clean it. Also, apply a thin coat of transparent nail paint/nail enamel on the ring's inner side to save it from being tarnished. ❥ You may request to return the products, 15 days after you received the items (Delivery Day).
